The comedian and actor hosted the annual music awards ceremony last year and also shared presenting duties with his Gavin and Stacey co-star Mathew Horne in 2009.
Corden said in a statement: "I enjoyed presenting the show so much last year, so being asked back for the third time is a real honour.
"Ever since I was a teenager, I've loved the Brit Awards. As a music fan I feel totally privileged to have the best seat in the house. I can't wait."
Corden reportedly donated his appearance fee for last year's event to Comic Relief.
Artist Sir Peter Blake - who famously designed the album artwork for Sgt Pepper's Lonely Hearts Club Band by The Beatles - has been commissioned to create next year's Brits statuette after fashion designer Vivienne Westwood was given the design brief for this year's trophy.
Blake described the Brits as "[a] most important and exciting music event", adding that he was enjoying the challenge of designing the trophy.
The Brit Awards are due to take place at The O2 in London on February 21, 2012. Tinie Tempah and Arcade Fire were the major winners at this year's ceremony, taking home two prizes each.
